Evening all,

As per the title does anyone know where I can source an extension bar for hole saws?

Scenario today: using 54mm hole saw through approx 300 mm wall made up with plasterboard with a ply backing, cavity, a layer of osb, insulation and then a brick outside wall
(Obviously aware you can’t use the hole saws on the brick)
Normal arbors just can’t get A deep enough reach
